MAC transmitted by the host, not only is the command abandoned but the cryptographic mode is

also reset. A new authentication is required to reactivate the cryptographic mode.

7.6 Initial Device Programming

CryptoRF is delivered with all security features disabled. To program the polling response or

enable the security features of CryptoRF the device must be personalized by programming sev-

eral registers. This is accomplished by programming the configuration memory using simple

write and read commands.

7.7 Transport Password

To gain access to the configuration memory, a transport password known as the secure code

must be presented using the Check Password command. The secure code for

AT88SC3216CRF is $60 78 AF.

8. Tuning Capacitance

The capacitance between the coil pins AC1 and AC2 is 82 pF nominal and may vary ±10% over

temperature and process variation.
